Order-statistics minimum error detector for optimal delay detection in multipath Rayleigh fading channel context
Résumé
In this paper, we address the problem of delay detection, for mobile localization, in a multipath Rayleigh fading context. A new methodology for delay detection, in presence of closely spaced interfering paths, is introduced, namely the order-Statistics Minimum Error Rate (OS-MER) detector, based on the minimization of the true error probability instead of minimizing only the miss probability for a constant false alarm rate. Results show that the OS-MER detector is well adapted to this kind of detection problem.
